Description
Die Erfindung bezieht sich auf eine Abgasreinigungsvorrich tung mit einem zweischaligen Außengehäuse, in welchem mit einer elastischen Mineralfasermatte, insbesondere einer sogenannten Quellmatte, wenigstens ein wabenförmig strukturierter Trägerkörper sowie ein- und ausgangsseitige innere Abschirmtrichter sowie ggf. Abstandsringe zwischen aufeinanderfolgenden Trägerkörpern gelagert sind.The invention relates to an exhaust gas purification device tion with a double-shell outer housing, in which with an elastic mineral fiber mat, especially one so-called swelling mat, at least one honeycomb structured support body as well as on the input and output side inner shielding funnels and, if necessary, spacer rings between successive carrier bodies are stored.
Ein erhebliches Problem bei der Herstellung solcher Abgas reinigungsvorrichtungen bereitet das Einbringen der inneren Teile, d.h. also der gasführende Innentrichter und ggf. Ab standsringe zwischen mehreren Trägerkörpern in das Gehäuse derart, daß die inneren Bauteile einerseits vollständig durch die elastische Mineralfasermatte umhüllt sind und an dererseits auch keine Falten entstehen oder Überlappungen auftreten, da an diesen Stellen während der Montage bzw. im Betrieb durch die Ausdehnung der Quellmatte bei Erhitzung zu große örtliche Spannungsspitzen auftreten könnten, die zu einer Zerstörung der Trägerkörper oder der Auskleidungs trichter führen. Berücksichtigt man dabei zusätzlich noch, daß die ja notwendigerweise an bestimmte Gegebenheiten der Bodenplatte, vorbeiführende Rohre, Kardanwellen od. dgl., anzupassenden Abgasreinigungsvorrichtungen relativ kompli zierte Querschnitte der Trägerkörper erforderlich machen und auf der anderen Seite bei doppelflutigen Anlagen durch die eingezogene Form die Umhüllung mit der Lagermatte noch zusätzlich erschwert wird, so ergeben sich insgesamt doch erhebliche Montageprobleme, die in jedem Fall auch die Aus schußrate beträchtlich erhöhen.A significant problem in the production of such exhaust cleaning devices prepares the introduction of the inner Parts, i.e. So the gas-carrying inner funnel and, if necessary, Ab stand rings between several carrier bodies in the housing such that the internal components on the one hand completely are covered by the elastic mineral fiber mat on the other hand, there are no folds or overlaps occur because at these points during assembly or in Operation due to the expansion of the swelling mat when heated too high local voltage peaks could occur destruction of the carrier body or the lining funnel. If you also take into account that the necessarily to certain circumstances of the Base plate, passing pipes, cardan shafts or the like, adaptable exhaust gas purification devices relatively complicated graceful cross sections of the support body required and on the other hand with double-flow systems the retracted shape the wrapping with the storage mat still is made more difficult, so there are overall considerable assembly problems, which in any case also the off Increase shot rate significantly.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Abgas reinigungsvorrichtung der eingangs genannten Art so auszu gestalten, daß eine exakte fehlerfreie Montage der Innen bauteile und der sie umhüllenden Mineralfasermatte im Ge häuse erreicht wird.The invention is therefore based on the object of an exhaust gas So cleaning device of the type mentioned shape that an exact flawless assembly of the interior components and the mineral fiber mat enveloping them in the ge home is reached.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß die Innenteile durch die mit einer wieder lösbaren Kle berschicht auf der Innenseite versehene Mineralfasermatte zu einer Baueinheit zusammengefaßt sind.To achieve this object, the invention provides that the inner parts by the with a removable Kle Mineral fiber mat provided on the inside are combined into one unit.
Durch die erfindungsgemäße Anordnung einer wieder lösbaren Kleberschicht auf der Innenseite der Mineralfasermatte kann diese unter Zusammenhalten der von ihr umhüllten Innenteile sauber um diese Teile herumgezogen werden und dabei infolge der Wiederlösbarkeit der Kleberschicht auch bei Bedarf die Matte wieder etwas abgezogen, nachgespannt oder gelockert werden, um einerseits die Bildung von Falten zu vermeiden und andererseits eine exakte Umhüllung zu erreichen, so daß die Kanten des Lagermatten-Zuschnitts exakt aneinander stoßen und somit weder ein Spalt entsteht, durch den Gase unbehindert und ohne Durchsetzung des Trägerkörpers sozusa gen im Bypass neben vorbei passieren können, noch gefürch teten Überlappungen und damit verbundene Spannungsspitzen zu befürchten sind. Ein erheblicher Vorteil bei der Montage liegt dabei in der Tatsache, daß die Umhüllung abschnitts weise erfolgen kann, so daß nicht wie bisher nach dem Um schlagen der Matte beim Ausrichten andere Stellen wieder auseinanderklaffen können und somit ständig nachkorrigiert werden muß.Due to the inventive arrangement of a detachable Adhesive layer on the inside of the mineral fiber mat can this while holding together the inner parts encased by it be neatly drawn around these parts and as a result the releasability of the adhesive layer, if necessary Mat pulled off again, tightened or loosened to avoid wrinkles and on the other hand to achieve an exact wrapping so that the edges of the storage mat cut exactly to each other collide and therefore neither a gap is created through which gases unhindered and without enforcing the carrier body so to speak pass in the bypass next to, still fearful overlaps and associated voltage peaks are to be feared. A significant advantage in assembly lies in the fact that the wrapping section can be done wisely, so that not as before after the order hit the mat again while aligning can diverge and thus constantly corrected must become.
In Ausgestaltung der Erfindung kann dabei vorgesehen sein, daß die Mineralfasermatte mit einer die Kleberschicht tra genden Gewebeschicht kaschiert ist. Eine derartige Gewebe schicht hat den Vorteil, daß das Aufbringen der Kleber schicht einfacher ist als dies der Fall ist, wenn man den Kleber unmittelbar auf die weiche saugfähige Quellmatte aufbringt. Die benötigte Klebermenge - hierfür eignet sich beispielsweise ein Acryl-Latex-Dispersionskleber - ist so mit geringer.In an embodiment of the invention, it can be provided that the mineral fiber mat is laminated with a fabric layer that carries the adhesive layer. Such a fabric layer has the advantage that the application of the adhesive layer is easier than is the case if the adhesive is applied directly to the soft, absorbent swelling mat. The amount of adhesive required - for example, an acrylic latex dispersion adhesive - is less.
Vorteilhaft bezüglich Klebermenge und Herstellung ist die Verwendung von doppelseitigen Klebefolien (Klebebändern), die unmittelbar vor dem Stanzen der Keramikfasermatten-Zu schnitte beim Abwickeln der Mattenrollen mit den Matten verklebt werden können.This is advantageous with regard to the amount of adhesive and production Use of double-sided adhesive films (adhesive tapes), the immediately before punching the ceramic fiber mat-Zu cuts when unrolling the mat rolls with the mats can be glued.
Neben der Möglichkeit, die Kleberschicht von einer Abzieh folie aus Papier, Kunststoff od. dgl. zu überdecken, so daß die fertigen Zuschnitte beliebig zur Verarbeitungssta tion transportiert werden können, da die Abziehfolie ja erst unmittelbar vor dem Umhüllen der Innenteile einer Abgasreinigungsvorrichtung abgezogen wird, hat es sich auch als sehr zweckmäßige Alternative erwiesen, die fertigen Zu schnitte der Mineralfasermatte im Zuge der Montagestraße mit einer Kleberschicht zu versehen, die Kleberschicht in einer vorzugsweise als Infrarot-Heizeinrichtung ausgebilde ten Heizzone anzutrocknen und den Zuschnitt unmittelbar da nach in die Verarbeitungsstation einzubringen, um die dar auf aufgelegten Innenteile durch Umschlagen des Zuschnitts zur einfach verarbeitbaren und problemlos in das Außenge häuse einlegbaren Baueinheit zusammenzufassen.In addition to the ability to peel off the adhesive layer to cover film made of paper, plastic or the like, so that the finished blanks can be used for processing tion can be transported, since the peel film yes just immediately before wrapping the inner parts of one Exhaust gas purification device is removed, it has also proved to be a very useful alternative, the finished Zu cuts of the mineral fiber mat in the course of the assembly line to be provided with an adhesive layer, the adhesive layer in one preferably designed as an infrared heating device drying zone and the cut immediately there after to bring into the processing station to the on the inner parts by turning the blank for easy processing and easy in the outside area summarize housing insertable unit.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Aus führungsbeispiels sowie anhand der Zeichnung. Dabei zeigen:Further advantages, features and details of the invention result from the following description of an off management example and based on the drawing. Show:

Fig. 3 einen vergrößerten Teilquerschnitt durch eine erfin dungsgemäß ausgestaltete elastische Mineralfasermat te und Fig. 3 shows an enlarged partial cross section through an inventively designed elastic mineral fiber mat and
Fig. 4 den Zuschnitt der Mineralfasermatte zur Umhüllung der Innenbauteile der Abgasreinigungsvorrichtung nach den Fig. 1 und 2. Fig. 4 shows the blank of the mineral fiber web for covering the internal components of the exhaust gas purification apparatus according to FIGS. 1 and 2.
Die Fig. 1 und 2 zeigen eine Abgasreinigungsvorrichtung, in deren aus zwei Halbschalen 1 a und 1 b bestehendes Außenge häuse 1 die Innenbauteile unter Zwischenordnung einer sich über die gesamte Länge erstreckenden durchgehenden Mineral fasermatte 2, vorzugsweise einer sogenannten Quellmatte, gelagert sind. Die inneren Bauteile umfassen dabei im dar gestellten Ausführungsbeispiel zwei hintereinander lie gende, durch einen vorzugsweise keramischen Abstandsring 3 getrennte wabenförmig strukturierte Trägerkörper 4 u. 4′, die üblicherweise mit einer katalytisch wirksamen Beschich tung versehen sind, sowie jeweils die konischen Abgaszuführstutzen 5 und Abgasabführstutzen 6 in Abstand überdeckende innere Abschirmtrichter 7 u. 8. Figs. 1 and 2 show an exhaust gas purification apparatus in which two half-shells 1 a and 1 b existing Außenge housing 1, the internal components with the interposition of a line extending over the entire length of the continuous mineral fiber web 2, preferably a so-called swelling mat are mounted. The inner components in the illustrated embodiment comprise two consecutive lying, separated by a preferably ceramic spacer ring 3 honeycomb structured support body 4 u. 4 ', which are usually provided with a catalytically active coating device, and each the conical exhaust gas supply nozzle 5 and exhaust gas discharge nozzle 6 at a distance covering inner shielding funnel 7 u. 8 .
Zur einfacheren Montage ist die Mineralfasermatte 2 auf ih rer Innenseite mit einer wieder lösbaren Kleberschicht 9 versehen, so daß mit dem Umhüllen der Innenbauteile 3, 4, 7 u. 8 durch die Mineralfasermatte diese Innenbauteile auch zu einer Baueinheit zusammengefaßt werden, welche sehr viel einfacher weiter verarbeitet werden kann, da sie beim Ein legen in die untere Halbschale 1 a des Außengehäuses und dem Auflegen der oberen Halbschale 1 b bis zum Verschweißen der Ränder 10 u. 11 in der Montageposition zusammengehalten werden und auch ein Aufklaffen der Mineralfasermatte, bei der möglicherweise ein durchgehender Spalt entstehen könnte, durch welchen das Abgas an den katalytisch be schichteten Trägerkörpern vorbeigeleitet werden könnte, vermieden wird. In Fig. 3 erkennt man eine Ausführungsform einer Mineralfasermatte, bei der die Kleberschicht 9, bei spielsweise eine Schicht aus einem Acryl-Latex-Dispersions kleber, von einer abziehbaren Schutzfolie 12 überdeckt ist, die erst unmittelbar vor dem Umhüllen der Innenbauteile der Abgasreinigungsvorrichtung abgezogen wird. Auf diese Weise können die Zuschnitte der Mineralfasermatte, wie sie in Fig. 4 dargestellt sind, an beliebiger Stelle und zu belie bigen Zeiten vor der eigentlichen Endmontage bereits vorbe reitet werden. Die Kanten 13 bzw. 14, 16 bzw. 17, 15 bzw. 18, 19 bzw. 22 und 20 bzw. 21 des in Fig. 4 gezeigten Zu schnitts lassen sich durch die wieder lösbare Kleberschicht 9 problemlos exakt auf Stoß aneinanderdrücken und behalten diese Montageposition auch im Einbauzustand dauerhaft bei.For easier assembly, the mineral fiber mat 2 is provided on its inner side with a releasable adhesive layer 9 , so that with the wrapping of the inner components 3 , 4 , 7 and. 8 by the mineral fiber mat, these internal components can also be combined to form a structural unit, which can be processed much more easily, since they can be inserted into the lower half-shell 1 a of the outer housing and the upper half-shell 1 b until the edges 10 are welded together . 11 are held together in the assembly position and also a gaping of the mineral fiber mat, in which a continuous gap could possibly arise, through which the exhaust gas could be guided past the catalytically coated carrier bodies. In Fig. 3 you can see an embodiment of a mineral fiber mat, in which the adhesive layer 9 , for example a layer of an acrylic latex dispersion adhesive, is covered by a removable protective film 12 , which is only removed immediately before wrapping the inner components of the exhaust gas cleaning device . In this way, the cuts of the mineral fiber mat, as shown in Fig. 4, can be prepared at any point and at any time before the actual final assembly. The edges 13 or 14 , 16 or 17 , 15 or 18 , 19 or 22 and 20 or 21 of the section shown in FIG. 4 can be easily pressed together precisely by the releasable adhesive layer 9 and keep them together Installation position permanently even when installed.
